Abstract: A shaft seal for sealing fluids includes a rotating shaft means having an axis and an external cylindrical surface. A seal ring is disposed about the shaft and has an internal cylindrical surface juxtaposed to the external cylindrical surface and mating therewith to form mating cylindrical surfaces. One of the cylindrical surfaces is a smooth cylindrical surface, and a plurality of spaced, generally parallel indentations are formed in the smooth cylindrical surface, the indentations extending at an acute angle relative to the axial direction of the shaft such that fluid entering the mating cylindrical surfaces is returned by the indentations as the shaft rotates.

Abstract: Provided is a sealing device that increases the lubricity of seal surfaces, prevents leakage of sealed fluids, and prevents excessive heat generation and excessive friction at seal surfaces. Said sealing device, which is of the type that seals a fluid trying to leak from the outer periphery of a sealing surface towards the inner periphery thereof, forms at least two dimples in a circumferential direction in each of a plurality of rows arranged in a radial direction on a sealing surface of a stationary-side sealing element or a rotating-side sealing element. Each dimple is tilted by a dimple angle θ between 0° and 90°, exclusive, such that the tip of that dimple in the direction of rotation is tilted toward the inner periphery side. In each of the plurality of rows of dimples, land areas are formed in the circumferential direction between the proximate tips of adjacent dimples. For each of the plurality of rows of dimples, if a circle is drawn through the centers of the dimples in that row, let L1 be the distance along the circle from the point the circle enters a dimple to the point the circle leaves that dimple, and let L2 be the length, along the circle, of the land areas between dimples. The dimples are characterized by being arranged such that the gap ratio L1/L2 is between 0.001 and 0.1, inclusive.

Abstract: Primary objective of the present invention is to provide a seal device wherein the seal surfaces of the device are always brought into close contact against the side walls of the mounting slot regardless of fluid conditions. The seal device has two seal portions located to both sides of a bight shaped elastic portion which has a “U”-shaped cross section wherein the respective seal portions have a first side portion and a second side portion. The second side portions of the seal portions abut against each other in a symmetric manner in order to form a “W”-shaped seal body element. The end portions of the both second side portions of the seal body element are joined and seal surfaces are defined on the outer side surfaces of the both first side portions.

Abstract: The object of this invention is to provide a structure of seal ring, and seal structure using the seal ring for flange joints of composite tanks and pipes, that prevents seal surface variations due to differences in thermal contraction between the seal ring and the tank/the flange joint, etc., that improves the resilience of the seal, and that prevents gas leakage due to poor sealing, in order to achieve the stable sealing. The seal ring fits into a ring groove formed in a sealed unit such as a tank unit or a flange joint to provide a tight seal to contain fluids. The heart-shaped seal ring has three curved surface areas that smoothly flow together, comprised of a first curved seal surface which contacts the formed surface of the ring groove, a second curved seal surface which contacts the seal surface of a second member (e.g. manhole cover), and a projecting curved surface on the opposite side. The foregoing seal ring is provided with a hollow cavity formed with the three curved surfaces of uniform thickness, and an indent that passes through from the hollow to the fluid introduction side.
